The subject inducts digital time division technology ( pwm ) , which is more advantageous at the accuracy and the predigest of hardware than simulant multiplication . what they call measuring power energy reasonably is that measuting except harmonics power energy fed back power . yet it realizes reasonable measurement of power energy which measures by base wave ac parameters method base on digital time division 本課題引入了數(shù)字時(shí)分割( pwm )脈寬調(diào)制技術(shù),在測(cè)量的準(zhǔn)確性、硬件電路的簡(jiǎn)化等方面都比模擬乘法器具有較高的優(yōu)越性。所謂合理的計(jì)量電能,就是不計(jì)非線性負(fù)載回饋給電網(wǎng)的負(fù)的諧波電能,而采用基于數(shù)字時(shí)分割的基波交流參數(shù)測(cè)量的方法,真正實(shí)現(xiàn)了電能的合理計(jì)量。
This product nutrition ingredient structure is good , the widespread use feed small wheat bran , the fine rice bran , the corn and the common distiller ' s grain powder protein content high , the crude fiber germany content is more moderate than , front several kind of feeds belong to the energy feed and the coarse fodder , but this product belongs to the protein feed , specially the amino acid content is other several kind of feed 3 ~ 5 times , moreover real protein proportion big ( amino acid total content / thick protein content = 73 . 6 % ) , must the amino acid type multi - content be high 該產(chǎn)品的營養(yǎng)成分結(jié)構(gòu)好,比廣泛使用的飼料小麥麩、精細(xì)米糠、玉米和一般酒糟粉的蛋白質(zhì)含量高、粗纖維德含量適中,前面幾種飼料屬于能量飼料和粗飼料,而該產(chǎn)品屬于蛋白質(zhì)飼料,特別是氨基酸含量是其他幾種飼料的3 ~ 5倍,而且真蛋白的比例大(氨基酸總含量/粗蛋白含量= 73 . 6 % ) ,必須氨基酸的種類多含量高。
